Europe’s defence technology sector is experiencing unprecedented momentum as geopolitical tensions reshape investment priorities across the continent. Traditional venture capital firms are pivoting towards dual-use technologies, whilst specialised funds emerge to capitalise on the estimated €500 billion European defence modernisation market over the next decade.
London-based Keen Venture Partners has secured €150 million for what it claims is Europe’s largest dedicated DefenceTech fund, marking a significant milestone in the maturation of European military technology investment. The fund received backing from the European Investment Fund alongside several undisclosed institutional investors, positioning Keen as a major player in the rapidly expanding sector.
DefenceTech fund raising reflects strategic European priorities
The European Investment Fund’s participation signals institutional recognition of defence technology as a strategic priority for European autonomy. Unlike traditional Silicon Valley defence investors focused on large-scale contracts, Keen’s thesis centres on dual-use technologies that serve both civilian and military applications—a distinctly European approach that navigates complex regulatory frameworks whilst maximising commercial potential.
“Modern battlefield requirements are evolving faster than traditional defence procurement cycles can accommodate,” explains the investment team. “We’re backing founders who understand that today’s conflicts demand software-first solutions, autonomous systems, and cyber resilience capabilities that can be deployed rapidly across multiple domains.”
This €150 million represents more than double the typical European defence-focused fund, reflecting both increased LP appetite and the scale of opportunities emerging across the continent. The fund’s structure accommodates longer development cycles typical of defence applications whilst maintaining the growth trajectory expectations of institutional investors.
European DefenceTech ecosystem gains institutional momentum
Keen’s strategy targets startups developing autonomous systems, cybersecurity infrastructure, satellite communications, and advanced materials—sectors where European companies increasingly compete with established US and Israeli defence contractors. The fund’s European focus addresses a critical gap in defence technology financing, where American investors often require US-centric business models that limit European market penetration.
The timing proves strategic as NATO’s Defence Innovation Accelerator ramps up activity and member states increase defence spending commitments to 2% of GDP. European governments are actively seeking indigenous alternatives to reduce dependence on non-EU defence suppliers, creating substantial market opportunities for portfolio companies that can navigate complex certification processes.
Portfolio construction will emphasise companies with proven dual-use applications, regulatory compliance expertise, and scalable technologies adaptable to different European markets. This approach differentiates Keen from generalist VCs attempting to add defence exposure through occasional investments in the sector.
This fund launch reinforces Europe’s emergence as a serious player in defence technology innovation, moving beyond traditional aerospace and shipbuilding towards the software-defined capabilities that will determine future military effectiveness. For European defence startups, access to dedicated capital with sector expertise removes a significant barrier to scaling within the continent’s complex regulatory and procurement environment.
